TRANSFERRING DEVICE FOR BRICK-MACHINES.

SPECIFICATION forming part of Letters Patent No. 732,221, dated June 30,1903. Application filed August 22 1902. Renewed May 2, I9 03- Serial No.155,427. (No model.)

To all whom it may-concern:-

Be it known that I, ALPHONSE F. POTVIN,

of Plaistow, county of Rockingham,'State of New Hampshire, haveinventedan Improvement in Transferring Devices for Brick-Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

In that class of brick-machines which deliver the bricks onto an endlesscarrier as fast as they are molded it has been customary to employ anumber of workmen to remove the bricks from the carrier by hand and loadthem onto trucks, so that they may be carried to the yard where they aredried. This method is objectionable in that the green bricks are oftendamaged by the fingers of the workmen in transferring them from thecarrier to the trucks and in that it requires the services of aconsiderable number of men to remove the bricks from the carrier as fastas they are delivered thereon by the machine.

The object of my invention is to provide a device for transferring thebricks from the carrier to the trucks which will make it unnecessary forthe workmen to touch the bricks with their -.hands and which will enablea single workman to transfer the bricks from the carrier to the trucksas fast as they are delivered thereon by the machine, even if themachine delivers the bricks to the carrier with much greater frequencythan has previously been customary. I accomplish this Object bydisposing a brick-obstructing wall crosswise the smooth-surfaced endlesscarrier of a brick-molding machine, which causes the bricks to becollected close together on the carrier while the carrier slides underthem, and by employing in connection therewith an elongatedbrick-engaging device, which is located at one side of the carrier andis movable across it, whereby the workman can discharge all the brickswhich have been thus collected from the carrier to the platform of thetruck.

The particular means which I preferably employ in carrying out myinvention is illustrated in the accompanying drawings, in which- Figure1 is a perspective view showing my invention. Fig. 2 is an endelevation, and Fig. 3 is a plan view thereof.

In the drawings, a indicates the endless carrier of a brick-moldingmachine havinga smooth oily surface, on which the bricks aresuccessivelydelivered, so that they lie crosswise of the carrier. Thecarrier is driven in the direction of the arrows in Fig. 1, so that itis passed about a roll a at the end of its movement from the machine andthen returned to themachine. At one side of the carrier and extendinglengthwise thereof I provide a brick-engaging device, which preferablyconsists of a plate or board 19 of nearly the same length as theplatforms of the trucks ordinarily employed for conveying the bricksfrom the machine to the yard, andI also provide a brick-obstructing wall0, which is connected at one end to the end of the plate b next thepulley a, and extends transversely of the carrier and at right angles tothe plate I), the plate 0 being preferably as long as the carrier iswide, The lower edges of both plates are straight and smooth and occupythe same plane. Two parallel arms e e are rigidly secured to the backside of the plate I) and extend rearwardly therefrom at a level which isbut slightly below the upper edge of said plate. A second pair of arms(1 d are also rigidly secured to the back side of the plate I) andextend over the upper edge thereof in the opposite direction from thatof the arms 8 e, the ends of said arms d 01 being connected by a handleor cross-bar d A pair of standards f f are arranged at the rear side ofthe carrier, and arollerg is journaled therein with its axis of rotationparallel to the direction in which the carrier is driven. The roller gis of such size and so arranged that when the arms 6 e are restingthereon and the lower edge of plate I) is on a level with or resting onthe carrier said plate 6 will be substantially perpendicular to its sureface. The roller 9 is provided with a pair of circumferential flanges gg which are preferably beveled on their adjacent sides, the distancebetween said flanges being some- I what greater than the distancebetween the outer sides of the arms a e, so as to permit dotted lines inFig. 3.

A stop 0 is rigidly supported by the standard f and projects for a shortdistance across the face of the carrier, as shown in Fig. 3, said stop0' being so arranged that it will engage the side of the plate 0 nextthe pulley a and closely adjacent to its point of connection with plateb when said plates is in a position at right angles to and disposedcrosswise the carrierand the adjacent arm 3 is resting against theadjacent flange g of roller 9.

A pair of brackets h h are secured to the supports f f, respectively,their upper surfaces being on a level with or slightly above the uppersurface of the carrier and extending from said surface to points nearthe adjacent edge of the carrier. A shelf is rigidly supported on alevel with the upper surface of the carrier or slightly below saidsurface and on the opposite side of the carrier from the brackets h h.

'm indicates the platform of a truck, which is preferably employed forconveying the bricks from the carrier to the yard, said platform beingsubstantially on a level with the shelf 7c, so that the surfaces of thecarrier a, shelf k, and platform m may form practically one continuoussurface.

In normal operation the molding-machine delivers the green bricksrapidly upon the carrier, so that they are usually from onefourth of aninch to one inch apart. The lower edges of plates 1) and c arepreferably allowed to rest upon the carrier, the side of the plate 0resting against the stop a and the plate b extending longitudinally andplate 0 transversely of the carrier. The first brick which is dischargedupon the carrier is carried along until it is stopped by the plate a,said plate engaging one side of the brick throughout its entire surface.As the carrier is smooth and oily, it readily slides under the brick, sothat the latter is held in this position. ried against the first, andthe succeeding bricks will be successively stopped in like manner untilsuch a number have been collected that their combined thickness issubstantially equal to the length of the plate I). The operator thendraws the plates 12 and c forwardly across the carrier by handle d ontothe shelf 70 and platform m of the truck, causing the bricks which havebeen collected in front of the plate b to slide from the carrier ontothe shelf 70 and then onto the platform of the truck. The operator thenlifts up and pushes back on the handle (1 leaving the bricks upon thetruck and lifting the plate b above the bricks, which by this time willhave advanced to a point nearly opposite the middle of said plate. Whenplate I) has been pushed back over the bricks, it is lowered until bothplates rest upon the carrier with the rear end of the plate 0 pressedagainst the stop 0' before the first brick can The second brick will becar-' reach the plate 0. The bricks will then be collected again by theplate 0 in front of the plate I), as before described. If the bricks arebeing delivered rapidly upon the carrier, the operator will not be ableto draw the plate 17 directly across and completely therefrom before thenext brick to those which are being removed will be carried against theend of plate I). For this reason the stop a is made so that it onlyprojects partly across the carrier, thereby enabling the operator assoon as he has moved the end of the plate a beyond the end of the stopto draw said plates longitudinally of the carrier while he is drawingthem across the same, so that they will move in an oblique direction, asindicated in the dotted position in Fig. 3,and the plate I) will notinterfere with'the succeeding bricks on the carrier while it is beingdrawn therefrom.

While it is generally more convenient to rest both plates 1) and c onthecarrier while the bricks are being collected, yet plate I) may bemoved back so that it rests on brackets h h, if desired, so that therewill be no friction between it and the carrier. (See Fig. 2.) In suchcase the stop 0' may be shortened so that it does not project across thecarrier at all. However, it has been found to be more convenient anddesirable to have the support for the plate 0 as nearly in line with theforce which is applied thereto as is practicable.

The arms e 6' must extend rearwardly from plate I) at such a distanceabove its lower edge that the bricks on the carrier will pass under saidarms while the plates are being drawn onto the truck.

While I have shown a device of simple construction for transferring thebricks from the carrier to the truck, it will be apparent that devicesof other constructions which perform similar functions may be readilyproduced, and I therefore do not wish to limit myself to the exactconstruction herein shown and described. It will be apparent, forexample, that the plate I), which comprises the principal portion of thebrick-engaging device, may be used without the plate 0, which comprisesthe principal portion of the brick-obstructing wall; but as the bricksare usually delivered somewhat irregularly the collecting device is verydesirable, particularly as the bricks will be loaded onto the trucksclose together, enabling them to be more fully loaded than is usual whenthey are loaded by hand.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with the endless carrier of abrick-machine, of anelongated transversely-movable brick-engaging device 10- cated-at oneside of the carrier and extending lengthwise thereof, which engages aplurality of bricks on the carrier and moves themtransversely todischarge them from the carrier, substantially as described.
